To all whom t may concern:

`Be it lnovvn that I, ROBERT M. LA SALLE, a citizeny of the United States of America, residing at .lilianin in the county of Gila and State of Arizona.7 have invented certain neiv and useful Improvements in, Steering Devices, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to steeringvdevices and has for its principal object the production of a structure'ivhich is so formed as to be easily applied to all self-propelled vehicles in such a manner as to ,permit the vehicles to very easily steered in a desired direction with the least possible energy for accomplishing this purpose,-While minimizing the4 nuniber of parts becoming broken when in operation.

Another object of this invention is the production ort a steering device which has a pin ,extending through the axle upon. which the hubspindle is mounted so that this hub spindle inay pivot upon this `,pin as the steering device is operated, thereby Iperi-nitting the vehicle upon which the steering device is mounted to be easily directed asdesired.

A still further object of this inventionis the production of a' steering device which is constructedol a niininiuni nuniber of simple parts so asseinbled as to ininiinize the possibility of the device becoming out of Aorder when in operation. whereby the device may be in condition to be easily operated at all tirnes.V

l/Vith .these and other objectsinvievv this invention consists of certain novel combina? tions, constructions, .and arrangements of parts as will be hereinafter fully described and claimed.

1n the accompanying dravving: Figure l is a vertical section through the steering device as constructed in accordance with this invention.

Fig. 2 is a vertical section taken at right angles to Fig. 1, along the line 2 2 .of Fig. 1. Fig. 8 is a rear elevation of the steering device, the. axle being shown in section.

FigpeL is a horizontal Vsectional view of thel device, taken on the line 4-ft A'of Fig. l, thehub sleeve being removed.

Fig. 5 is a section takenV on the line 5 5 of Fig. l, loolyring in the directionv of the arrvv's5` the retaining nut being shown in 7elevation.

die'. n u Fig. 7 is a rear elevation of the hub spin.- c e. f

Fig. 8 is an elevation of the plate adapted Fig. c is a fop pian View of ai@ hub Spiato be attached to the ange of the yhub .spini dle showing' they spindle rod attached thereto. Fig. is `an enlarged fragmentary sectional vievv of a portion of the device, illustrating the inanner in which the spindle plate is connected Vto the hub spindle.. y

Fig. l0 is a detail perspective view of the pivot pin.

Fig. 1l is a detail perspective view of a certainjbushing used in connection With this invention. e Y y VReferring to the accompanying drawings by numerals it Will be seen that l designates the axle having the side ribs 2 formed thereon, which extend substantially throughout the entire length of the axleal'th'ough adjacent the ends thereof they terminate so as to perniit the body 3 having the central bore 4C to be formed thereon. The pin 5 as. shovvn in'Fig. l is .passed .through the bore 4 of the body 3 so as toy project for a distance above and belovv the axle l. as shown in Figs, f

l and 2. The set screw 6 is carried by the body 3 and passes into the socket T formed in the pin 5 there-by tinedly holding' the pin 5 in ak set position with respect to the body The .Washers 8 rare positioned upon the projecting ends of the pin 5 as shown in Figs. land 9. so as to bear upon the ends of the body 3. The bushings 9 are also po- Y sitioned yupon the projecting ends of the pin 5 and in turn bear upon the Washers S.

The ,hub spindle 10 is provided With, a circular rear vportion 11 which is adapted to encompass the body?) of the axle l. This circular' rear portion ll of the hub spindle 10 is provided Withl alined openingsy 12 in Which the projecting ends of .the pin 5 and idle/ X110 tapers 'toward its outer end so as' to kcomprise a. cone-like structure7 as shown incense at 13, Jfrom which extends the externally threaded neclr 14. rlhe circular rear portion of the hub spindle 10 is provided with an integral annular flange 15 formed thereon in Which there are formed a number ollopenings 16. r1` he inner portions of this rear circular portion 11 are beveled outwardly as indicated at 17, these outwardly beveled portions 17 being in alinement With each other andk through the center of these beveled portions there are formed deepened channels 18. Thus, it Will be seen that as the spindle 10 is turned in either direction by pivoting upon the pin 5 the beveled portions 17 Will accommodate the axle 1, While the channels 18 Will accommodate the ribs 2, thus permitting the spindle to move to a greater degree than 'would be the case it these beveled portions and channels were not provided. The spindle plate 19 is provided with an enlarged integral pocket 20 so that this spindle plate 19 may be positioned upon the flange 15 of the hub spindle as shovvn clearly in Fig. 3. This pocket 2O has a notch 21 at its inner portion communicating With a second notch 22, :which notch 21 corresponds in shape to one of the beveled portions 1T of the rear circular portion 11 of the hub spindle 10, While the notch Q12 Will conform in shape to one of the channels 18.

The spindle plate 19 is provided With a plurality of openings 23 which openingsQB are formed so as to register Tvith the openings 16 formed in the llange 15 when the spindle plate is positioned thereon. The bearing Washers f2-#l are then positioned upon the spindle plate 19 after which the machine screws are passed through the openings 23 and into the openings 16 which are internally threaded for Xedly holding the spindle plate 19 in a set position upon the rear port-ions ot the hub spindle 10. The steering rod 26 has a tori; 27 extending therefrom, which i'orlr 27 is secured in any suitable manner upon the spindle plate 19. As a consequence, when the rod 26 is swung in a desired direction the spindle plate 19 will in turn swing the hub spindle 10 in a desired direction inasmuch as the hub spindle as above set forth is pivotally mounted upon the pin 5. A bearing ball ring 28 is positioned upon the rear circular portion 11 the hub spindle 10 so as to bear against the forward sides of the annular flange 15 of the hub spindle 10. f1 ring 29 is positioned over the rear circular portion 11 of the hub spindle 10 although in spaced Vrelation vvith reference to the'ring 2S, whereby sufficient space is provided between these t-Worings, since they are internally beveled as shown in Fig. 1, thereby constituting a bearing ball race in which the bearing balls 30 are positioned. The hub sleeve 31 is positioned upon the hub spindle 10 since the interior of the hub sleeve 31 is formed so as to conform somewhat in shape to the outer periphery or the hub spindle 10. It should be noted that the sleeve 31 is provided With an annular groove 32 for the reception of the rings 28 and 29, thereby causing the hub sleeve to be rotatably mounted upon the spindle. This hub sleeve 29 is, of course, provided with parallel yflanges 33 between Which the inner ends of the spokes 34e are positioned, these spokes being retained in their correct engagement with the anges 33 by means of the bolts 35 passing through the flanges and also through the inner ends ot the spokes 34. The nut 36 may be positioned upon the externally threaded neck 14 so as to tit Within the flared outer end 37 of the hub sleeve 31, thereby retaining the hub sleeve upon the hub spindle 10. It is, of course, obvious that the flared outer end 37 of the hub sleeve 31 may be externally threaded so as to carry the dust cap 38, as shovvn in Fig. 1.

What is claimed is 1. ln a device of the class described, the combination ot a hub-spindle, said hubspindle provided with an annulartlange, said flange provided with opposite beveled portions, and With a channel in the center of each of said beveled portions, a plate provided with a steering-rod connection, said plate provided With a notch registering with one y ot the beveled portions of the flange, said plate also provided with a channel in the center ot the notch registering With the channel on said liange, means fastening said plate and flange together, a hubsleeve mounted upon said hub-spindle,.and an axle with side ribs movably mounted in said hub-A spindle.

2. ln a device of the class described, the combination of a hub-spindle, said hub-spindle provided with an annular flange at one end, said iiange provided with a rectangular opening. and at opposite sides of said opening are beveled portions, each beveled portion being provided With a central channel, a bifurcated plate provided With Lsteeringrod connection engaging said annular flange of said hub-spindle, said plate provided at its inner end with a socketportion and a channel, each registering with similar portions on said flange, means'securing the plate and flange together, a hub-sleeve mounted upon said hub-spindle, and an axle with side ribs movably mounted in the hub-spindle, substantially as shown and described.
